Surprising to me, considering our reputation for being a “car culture”, the interstates of Southern California are barely touched. I can easily get the 605, the 405, and the 710 around Long Beach. The others might have to wait a bit until I get free time. In general, the whole of the south end of Los Angeles County is scarcely mapped at all. Once I figure out how to get the Mapillary mount to work in my car (see separate post in Tools if you can help), I will get on it and start filling in the big blank.
